BALlNG-PRESS.

SPECIFICATION forming part of Letters Patent No. 368,393, dated August16, 1887.

Application filed February 5, 1887. Serial No. 226,700.

To all whom it may concern.-

Be it known that I, DAVID L. HANNAY, of Greenville, in the county ofGreene and State of New York, have invented a new and ImprovedBaling-Press, of which the following is a full, clear, and exactdescription.

Myinvention relates to balling-presses, more particularly of that classknown as continuous balers, and has for its object to provide a simple,comparatively inexpensive, and effective press of this character whichwill form compact bales with economy of time and labor of attendants.

The invention consists in certain novel features of construction ofparts of the press. especially of the plunger-actuating mechanism, allas hereinafter described and claimed.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts'in all the figures.

Figure l is a side elevation of the case or body portion of my improvedpress with the sweep partly broken away and the feed-door of the upperbaling-box open. Fig. 2 is a vertical sectional side elevation of thepress-case, partly broken away, and showing the plungers and theiroperating mechanism in other relative positions; and Fig. 3 is a detailplan view illustrating more particularly the connection of the sweep tothe cranked shaft which operates the two plungers of the press.

The press ease or body A is made with two baling boxes or chambers, B 0,one arranged directly over the other, and wherein, respectively, arefitted the plungers D E, which are connected by their pitmen F G,respectively, with oppositely-set cranks H I of a shaft, J, which is journaled at its center and upper and lower ends in the press-case frame,as most clearly shown in Fig. 2 of the drawings.

The baling-boxes B O are made tapering toward their outer ends, whichare open to allow discharge thereat of the bales after they are bound byties introduced at side slots, K, in the press-case walls, one tied balebeing forced out of the baling-boxes by the pressure of the plunger informing a bale behind it, and the rearward taper of the baling-boxesassures necessary resistance to the discharge of the bales to giveproper density to those being formed (No model.)

between grooved spacingblocks b c in the balingboxes, the operation inthese respects being similar to other presses of this class known ascontinuous baling-presses. Feed-doors L M are hinged at opposite sidesof the upper and lower balling-boxes, B C, respectively, to allow thehay, straw, or other material to be baled to be fed into the boxesbehind the plungers D E, operating therein, a button or latch, N, beingprovided on the case to hold either door or both doors closed.

The plungers F G are connected to the rounded wrists or crossbars of therespective cranks II I by metal shackles O, bolted to the ends of thepitmen. The sweep I, to the outer end of which the horse or horses willbe hitched for operating the press, is forked at its inner end,providing projecting arms p p, with a space or opening, 1), betweenthem. The ends of these arms pp abut one flat face of squared parts jjof the main crankshaft J, formed above and,below the central roundedpart, j, of the shaft, which has a bearing in the horizontal centralpart, a, of the presscase, and to these parts 1) p of the sweep, and tothe body of the sweep next to them, are fixed a couple of shackles orcoupling irons, R R, of] form, and the cross-bars r r of which restagainst the flat faces of the squared parts j of thecrank-shaft,direetly opposite the abutting ends of the arms pp of thesweep, while the opposite sides of the straps R R lap over the other twoopposite sides of the parts j of the shaft, and whereby the sweep willhave a very substantial connection to the shaft and project in a planeparallel with the reverselyset cranks of the shaft for turning it tooperate" the plungers in the press-case. The space p between thesweep-armspp allows the sweep to swing around as far as necessary toboth sides of the press-case without contact with the corner of thecentral part, a, of the ease, and the sweep will stop against the sidesof said part a of the case at the extremes of its stroke.

The cranks H I of the shaft J are arranged directly opposite each other;hence it will ap pear that while the plunger D is being forced rearwardto press material which had been fed into either upper door, L, of theupper baling-box, 13, the plunger E in the lower baling-box, G, will becarried backward,while the material which it had pressed will beheldfrom undue expansion by retainers S, of any approvedconstruction, fittedinto the walls of the baling-box, both boxes B 0 having these retainersfor a similar purpose.

It is obvious that the expansion of the hay or other material in eitherof the baling-boxes, and before said expansion is checked by theretainers S, will assist the forward or effective stroke of the plungerin the other box.

It will be seen that when the sweep is moved to its extreme of stroke ineither direction the cranks will not stand at or near their deadcenters,as in other presses, and this is due to the connection of the sweep tothe shaft about in the plane of the shaft-cranks; hence the pressure ofthe hay in expanding in one balingbox will have full effect in aidingthe effective stroke of the plunger in the other box, and the leverageof the cranks will be greatest when the most power is needed-viz., atthe extremes of movement of the sweep.

Bars T, fixed to the floors of the baling-boxes, form guides to theplungers and do not interfere with the feed of the material through theopen doorways, and the press may be fed from either side or both sidesof both the bali'ngboxes, thereby assuring rapid baling of the materialand effecting economy of time and labor in the work. Y

It will be understood that the press-case is to be mounted on a suitablewheeled truck, which is not shown in the drawings, and may be ofordinary or approved construction.

Having thus fully described my invention, I claim as new and desire tosecure by Letters Patent- 1. In a baling'press, the combination, withthe press case and a power-shaft journaled therein,and provided withreversely-set cranks connected to operate plungers in the case, of asweepv rigidly connected to the shaft in the plane of the cranks,substantially as shown and described.

2. A baling press constructed with two open-ended baling-boxes arrangedone over the other and provided with feed-doors, two plungers, onefitted in each box, pitmen connected to the plungers, a power-shafthaving reversely-set cranks to which the plunger-pitmen are connected,and a sweep, I, connected directly and rigidly to the shaft in the planeof the cranks, substantially as shown and described.

3. The combination, in a baling-press, of a case, A, having baling-boxesB 0, provided with doors, as L M, plungers D E, fitted therein, pitmen FG, connected to the plungers, a power-shaft, J, journaled in the caseand having reversely-set cranks H I, to which the pitmen F G areconnected, and a sweep, 1?, connected directly and rigidly with theshaft J inthe plane of the cranks, substantially asdescribed, for thepurposes set forth.

4.. In a baling-press, the combination, with a presscase andapower-shaft, J, j ournaled in the case and provided with reversely setcranks, and connected to operate plungers in the case, substantially asspecified, of a sweep, 1?, having a forked end providing armspp, whichabut flat faces of the power-shaft, and coupling-ironssecured to thesweep and bearing at their cross-bars r and at opposite sides upon otherflat faces of the shaft, said sweep being secured to the shaft to,project in the plane of the cranks thereof, substantially as shown anddescribed.

5. The combination, with a cranked powershaft of a baling-press, of asweep abutting by its end a flat face of the shaft, and 'couplingirons,as R, engaging the opposite fiat face and opposite flat sides of theshaft, and secured to the sweep to connect it rigidly to the shaft,substantially as shown and described.
